AUTOMATIC TURNTABLE OPERATION: Gently places the stylus (needle) on records for you and automatically returns the tonearm when record ends, so you don't need to manually reset it, the needle doesn't get damaged; Remark: AUTO STOP function only applies to most 33RPM vinyl records. THREE-SPEED TURNTABLE 33, 45, 78 RPM plays all of your vinyl records and favorite albums 3.5mm Aux-in and Built-in Bluetooth enables you play music from all of your favorite devices.

A Professional digital tracking force gauge designed for vinyl record purist's interested in precise measurement of vertical tracking force (VTF) at the correct vertical tracking angle (VTA). When used with the detachable cantilevered extension arm, the gauge closely approximates the vertical position of the stylus on the surface of a vinyl record when it is playing on a turntable- providing accurate "record-level" measurements of tracking force. For optimal accuracy, tracking force should be measured at the same vertical position as the record surface. With Riverstone's VTF gauge, tracking force is measured 2 mm - 3 mm from the surface of a turntable mat - the height of a stylus tip resting on an LP record (LP's have a thickness range of 1.9 - 2.9 mm). With less expensive gauges, the measurement distance is typically 6 mm- 8 mm. Precision strain gauge sensor provides 0.005 g measurement resolution and accurate measurements over the entire calibration range of the VTF gauge. Manufactured using non-magnetic materials (durable plastic housing with austenitic stainless steel cantilever extension arm). A polymer pad on loading platform protects the stylus tip and allows stylus centering on the measurement platform.
